Disorder of circulatory system Questions in English

(A) This condition is known as 'Angina Pectoris'. It occurs when there is an inadequate supply of oxygen to the heart muscles,leading to acute chest pain.
$(b)$ This condition is known as 'Hypertension' (High Blood Pressure),which refers to a persistent increase in systolic or diastolic blood pressure.

(A) Coronary artery disease,often referred to as $Atherosclerosis$,affects the vessels that supply blood to the heart muscle.
It is caused by the deposition of calcium,fat,cholesterol,and fibrous tissues,which makes the lumen of the arteries narrower.
This narrowing restricts the blood flow to the heart muscle,leading to various complications.

(D) High blood pressure,medically known as $Hypertension$,is a condition where the blood pressure is higher than the normal range $(120/80 \ mmHg)$.
$1$. It is indeed called $Hypertension$.
$2$. Persistent high blood pressure puts extra strain on the heart,leading to various heart diseases.
$3$. It causes damage to vital organs such as the brain and kidneys by affecting the blood vessels supplying them.
Therefore,all the given statements are correct.

(A) $CAD$ stands for Coronary Artery Disease.
It is a condition that affects the blood vessels of the heart.
It is often caused by the deposition of calcium,fat,cholesterol,and fibrous tissues,which makes the lumen of the coronary arteries narrower.

(B) Atherosclerosis is a specific type of arteriosclerosis characterized by the deposition of calcium,fat,cholesterol,and fibrous tissues in the lumen of arteries.
This deposition narrows the arterial lumen,thereby reducing blood flow and increasing blood pressure.
Hypertension refers to high blood pressure.
Angina pectoris is chest pain due to reduced blood flow to the heart muscle.
Arteriosclerosis is a general term for the hardening and thickening of artery walls.

(D) $Angina$ $pectoris$ is a disorder related to the heart.
When the heart muscle does not receive an adequate supply of oxygen,it results in chest pain,which is known as $Angina$ $pectoris$.
This condition arises due to a reduction or obstruction in blood flow to the heart muscles.
It is commonly observed in middle-aged and elderly individuals.
Therefore,all the given options are correct.

(D) Heart failure,sometimes known as congestive heart failure,is the state of the heart when it is not pumping blood effectively enough to meet the needs of the body.
It is different from cardiac arrest (when the heart stops beating) or a heart attack (when the heart muscle is suddenly damaged by an inadequate blood supply).
$A$. Angina pectoris is chest pain due to reduced blood flow to the heart.
$B$. Atherosclerosis is the deposition of calcium,fat,cholesterol,and fibrous tissues in the arteries.
$C$. Hypertension is high blood pressure.
Therefore,the correct option is $D$.

(C) Heart Arrest (Cardiac Arrest) occurs when the heart stops beating completely.
Heart Attack (Myocardial Infarction) occurs when the heart muscles are suddenly damaged due to an inadequate blood supply,often caused by blockage in the coronary arteries.
Therefore,option $C$ is the correct description.

(D) Coronary Artery Disease $(CAD)$,often referred to as atherosclerosis,affects the vessels that supply blood to the heart muscle.
It is caused by deposits of calcium,fat,cholesterol,and fibrous tissues,which make the lumen of the arteries narrower.
Therefore,the correct option is $D$.

(C) Cardiac arrest: It is a condition where the heart stops beating suddenly.
$(B)$ Heart failure: It is the state of the heart when it is not pumping blood effectively enough to meet the needs of the body.
$(C)$ Heart attack: It occurs when the heart muscle is suddenly damaged by an inadequate blood supply.
$(D)$ Angina: It is characterized by acute chest pain when no enough oxygen is reaching the heart muscle.
Therefore,the correct matching is $(A)-IV, (B)-I, (C)-II, (D)-III$.

(D) silent heart attack,also known as a silent myocardial infarction $(SMI)$,is a heart attack that lacks the classic,intense symptoms of a typical heart attack.
Statement $I$ is incorrect because the hallmark of a silent heart attack is the absence of typical,noticeable symptoms such as severe chest pain or acute shortness of breath.
Statement $II$ is correct because individuals experiencing a silent heart attack often exhibit very mild or atypical symptoms,such as fatigue,indigestion,or discomfort that is easily mistaken for other minor issues,leading the person to ignore the condition.
Therefore,statement $I$ is incorrect and statement $II$ is correct.

(C) Arteriosclerosis is the general term for the thickening,hardening,and loss of elasticity of the walls of arteries.
This condition restricts blood flow to organs and tissues.
Atherosclerosis is a specific type of arteriosclerosis where the hardening is caused by the buildup of fats,cholesterol,and other substances in and on the artery walls.
Bradycardia refers to a slower than normal heart rate.
Tachycardia refers to a faster than normal heart rate.
Therefore,the correct term for the hardening of arteries is arteriosclerosis.

(A) Atherosclerosis is a cardiovascular disease characterized by the hardening and narrowing of the arteries.
It occurs due to the deposition of calcium,fats,cholesterol,and other substances in the arterial walls.
This buildup,known as plaque,restricts blood flow and can lead to serious complications like heart attacks or strokes.
Therefore,the correct option is $A$.

(D) heart attack occurs when the heart muscle is damaged due to inadequate blood supply. This condition is medically known as $Myocardial \text{ } infarction$.
$Arteriosclerosis$ refers to the hardening of the arteries.
$Angina \text{ } pectoris$ is chest pain caused by reduced blood flow to the heart.
$Bradycardia$ refers to a slower than normal heart rate.

(B) Atherosclerosis is a specific type of arteriosclerosis characterized by the buildup of fats,cholesterol,and other substances in and on the artery walls (plaques).
This accumulation restricts blood flow and can lead to serious cardiovascular complications.
Arteriosclerosis is a general term for the hardening of arteries,while Arthritis refers to joint inflammation,and Angiogenesis is the formation of new blood vessels.

(A) $Angina$ $pectoris$ is a condition characterized by acute chest pain that occurs when the heart muscle does not receive enough oxygenated blood.
This condition is often caused by the narrowing of coronary arteries due to the accumulation of fat or plaque.
It is commonly described as a feeling of heaviness or pressure in the chest.
One of the hallmark characteristics of $Angina$ $pectoris$ is that the pain often subsides or disappears with rest,as the oxygen demand of the heart muscle decreases.

(A) Hypertension,or high blood pressure,is a condition where the force of blood against the artery walls is consistently too high.
$Atherosclerosis$ (buildup of fats/cholesterol in arteries),$Arteriosclerosis$ (hardening of arteries),and $Obesity$ are all known risk factors that contribute to increased blood pressure.
$Anemia$ is a condition characterized by a deficiency of red blood cells or hemoglobin,which reduces the oxygen-carrying capacity of the blood.
While $Anemia$ can lead to an increased heart rate to compensate for low oxygen delivery,it is not a direct cause of hypertension; in fact,severe anemia can sometimes lead to low blood pressure or hypotension.

(C) The correct option is $C$.
$Statement A$ is correct because atherosclerosis is indeed a condition where the arterial walls become thickened and lose their elasticity.
$Statement B$ is also correct because this thickening is primarily caused by the accumulation or deposition of fatty substances like cholesterol and triglycerides within the inner lining of the arteries.
Since the deposition described in $B$ is the direct pathological cause of the thickening described in $A$,$B$ is the reason for $A$.
